I have a universal spoke wrench. It used to work on any spokes I've owned, until now.
I have a bike with 2mm spokes. The nipples are between a 13 and 14 on the universal spoke wrench's sizes.
I have been able to find a mapping of gauge to mm/in.
I have not been able to find a definitive, trustworthy mapping of gauge/mm/in spoke measurements to gauge/mm/in nipple/spoke wrench measurements.
Can anyone please answer with a definitive, trustworthy mapping like this (except correct):
Spoke Gauge | in | mm | Nipple Gauge | in | mm
12 | .036 | 2.3 | 8 | .04 | 3.6
13 | .076 | 2.4 | 7 | .05 | 3.7
14 | .016 | 7.6 | 6 | .06 | 3.9
15 | .026 | 2.3 | 5 | .08 | 5.2
